Running Ubuntu's 4.11.0-6-generic kernel, whenever Facebook loads a webGL widget in Google Chrome my screen locks up for a few seconds. When it comes back, Chrome reports that webGL has crashed and I see this in the kernel log:
[121807.432832] drm/i915: Resetting chip after gpu hang [121807.433343] [drm] RC6 on [121807.448255] [drm] GuC firmware load skipped [121819.496336] drm/i915: Resetting chip after gpu hang [121819.496482] [drm] RC6 on [121819.516308] [drm] GuC firmware load skipped
I've attached the contents of /sys/class/drm/card0/error.
